DRAFT REGULATOR;

Application lfiled J'anuary'l', 1923. Serial No. 613,184.

To all tf1/0m t may concern.'

Be it known that we, JOHN E. McLEoD and ARTHUR J. Hnwrrr, Citizens ofthe United States, residing at l/Vashington, in the county ofTWashington and yState of Kansas, have invented certain new and .usefulImprovements in Draft Regulators, of -which the following isaspecification.

Our invention relates to .durft-regulating devices and is intended moreparticularly for use in connection with brooderswfor ponltry to controlthe temperature therein.

In the accompanying drawings, Aone embodiment of the invention isillustrated and:

Figure 1 isa vertical sectional view of a brooder with our inventioninstalled,

Figure 2 is a fragmentary side elevation in larger scale of thedraft-regulating device,

Figure 3 is a perspective view of the smoke damper of the furnace, i.

rFigure 4 is a perspective view of the ydetails of the damper, and

Figure 5 is a side elevation of one of the implements used in connectionwith the furnace.

Referring particularly to 'Figure 1 of the drawings, the referencenumeral repre-- sents a chicken house or broeder with a floor 11consisting of a thick layer of sand or gravel. rlChe reference numeral12 represents a furnace which is here-shown in the shape of an invertedconic frustum built of masonry and sunk to about threefourths of its-height into the ground. The top and bottoni of the furnace are openand. the top edge of the masonry is covered. by acastiron ring 13 havinga depending lip 14 engaging around the inner edge of the furnace and anupwardly directedv annular flange 114 adapted to engage with aIcorresponding fiange 15 on the cover or-lid 16. By this arrangement,thetop opening of the furnace is entirely closed. Y

At the bottoni of the furnace, where it is considerably smaller indiameter than at the topa grate 17 is located. Around the top edgeof thegrate is a rim 9 about three fourths of van inch in height, intended tokeep the coal from blowing of when the grate is removed. Below the grateis arranged an ash pit 18 with an ash pan 19 practically filling thepit. The ash pan is provided ywith handles 2O so that it may be liftedout of the furnace by means of a hook 21 `(see Figure especiallyprovided for this purpose, after the lid 16 and the grate 17 have beenremoved. The grate 17 may also'be lifted lout by the same hook 21.

At one side of the furnace, aboutniidway between the .grate and the lid,we provide a damper consisting of a slidable door 22 covering theopening of a manifold 23 comn'iunicating with the furnace. As best seenin Figures 3 and 4, this manifold is constrncted of an. upper Yplate 24and a `lower plate 25 having interengaging flanged sides and backproviding tubularoutlets 26 adapted'to engage the flue pipes 2.7 arepreferably two in the manifold. here be noted that the iianged sides ofthe plates will prevent warping of the manifold. The forward side of themanifold is curved to conform to the contour ofthe furnace `into whichit opens and the damper 22 is similarly curved and preferably providedwith reinforcing ribs 28 and a hinge 29A located at the top edge of thedamp-er and in the middle thereof. To this'hinge is pivoted a two-armlever 129 fulcrumed at 30 yin the housing J31 connected With themanifold in any sui-table manner such, for instance, as by meansof aU-belt 32. This housing consists of two Vinter-engaging plates 33 and 34and is closed at its rear end by means of an angular bracket 35 providedwith a perpendicular pipe A3G forming a `guide for the operating rod 37which is hinged to the inner end .of .the lever 129V as at 38. Theplates 33 and 34 of the housing and the top plate 24 of-tliemanifold, aswell as the end bracket 35, are provided with interengaging lugs 136 toform a rigid construction. At the upper end of the pipe 36 is kprovidedone or more prongs 39 intended to receive the ear 40 of a clampinghandle lever 41 .which embraces vthe operating rod V37. Between theupper end of the .pipe 36 and the lever 41, and surrounding Vthe rod 37,is inserted a coiled spring 42 .which tends to tilt the clamping lever41 upwardly and in that manner retain the operating rod 37 in any setposition. The upperend of the oper-at ing rod 37 carriesa ball forming agrip 43 for hand operation and it will now be seen that by pulling orpushing on the grip 43, the opening or closing of the damper door 22will be effected by hand, through the intermediary of the lever 129andthe rod 37. However, inforder to close the damper 22, vthe clampingil'iandle 41 will have to be depressed `to release .its hold on theoperating r, of which there It will Cil lli
